Bontrager
Race Thermal Wool 5 Socks

Details

Wool rules. It dries quickly, doesn't get stanky as easily, keeps you cool in the summer, warm in the winter and insulates even when wet. Bontrager's Race Thermal Wool Socks sport arch compression for a stay-put fit, and a cushioned bottom for extra warmth and comfort on every winter ride.

I own several pairs of these socks and swear by them. Wear them on their own for cool rides and layer with booties for cold days. I also wear them casually during the winter months. The socks are thin for wool socks. Very lightweight and built Bontrager tough.
